The YMCA Step Test and the Rockport Walk Test are both submaximal fitness assessments designed to estimate cardiorespiratory endurance, a key component of overall health. The YMCA Step Test evaluates how quickly the heart rate recovers after a standardized stepping exercise, providing insight into cardiovascular efficiency and aerobic fitness. In contrast, the Rockport Walk Test estimates a person's maximal oxygen uptake (VO₂ max) based on the time it takes to walk one mile briskly, the individual's heart rate at the end of the walk, age, weight, and gender. Both tests offer practical, accessible ways to assess fitness levels, particularly for individuals who may not be suited for high-intensity or laboratory-based testing.

Determining an estimated one repetition max (1RM) using a submaximal weight is a safer and more practical approach than performing a true 1RM test, especially for beginners. True 1RM testing requires maximal effort and proper technique under heavy loads, which can increase the risk of injury for individuals who are still developing strength and skill in a given movement. An estimated 1RM calculator allows users to lift a lighter, more manageable weight for multiple repetitions—typically between 3 to 10 reps—and uses that performance to predict their maximal strength. This method provides valuable insight into strength levels while reducing physical strain and supporting safer progression in training programs. We recommend doing this with compound movements like squats, deadlifts, bench press, etc. but it also works well with certain machines in the gym like leg press and chest press. While you can use it for simple movements like biceps curls, it's generally not recommended since the loads are much lower when compared to what you can actually do in a more complex compound movement
